"Go out one clear starlit night to some open space and look up at the sky, at those millions of worlds overhead. Remember that perhaps on each of them swarm millions of beings, similar to you or perhaps superior to you in their organization. Look at the Milky Way. The earth cannot even be called a grain of sand in this infinity. It dissolves and vanishes, and with it, you. Where are you? And is what you want simply madness?
"Before all these worlds ask yourself what are your aims and hopes, your intentions and means of fulfilling them, the demands that may be made upon you and your preparedness to meet them.
"A long and difficult journey is before you, you are preparing for a strange and unknown land . . .
"Remember where you are and why you are here.
"And now you can set out on the way."
